Yaesu G-5500 az issue
I removed the rotor from the tower today and started working on the azimuth rotor. When power is applied via left or right control the motor is running. I carefully split the case and everything appears intact. Grease is still good, no missing gear teeth, no metal shavings in bottom of housing. So the problem is somewhere in the gearing, or mechanical control. I would like to proceed further but have no exploded view of the inside of the rotor. I wouldn't want to proceed without some kind of service manual part description view. Does anyone have anything that might help? Does anyone have a clue, maybe had this same problem and fixed it?I already have the useless Yaesu user manual..

Hi Dave, I saw that. My problem I hearing from a private reply is in the clutch. I also discovered from a direct reply back to me there is an exploded view in the G-5400 manual. See…..

Good ol FoxDelta saved the day!
I’m going to get back on it tomorrow morning and see if my G-5500 is close enough to the diagram to take apart. I’ll report back here to the group with my findings….

If that's (clutch) the problem, a replacement from Yaesu was not available (call as this may have changed).
I got a pinion gear from a micromachine shop over in England. Like $15 including shipping. Not an exact fit, but very, very close.
The load (antennas) need to be well balanced for this to work. Motor won't start a pre loaded gear train.

I am once again upset with Yaesu. After removing sat antennas from my tower, removing the rotor, completely disassembling the azimuth rotor and guess what I find? A loose set screw. After taking everything apart I discover Yaesu used a set screw to fix the primary pinion gear to the motor. I mean, how stupid is that. I was really pissed, if I was the engineer in charge of the design of the drive system I would of spec'd a drift pin. A set screw really. So I cleaned everything off, applied some blue Locktite, noe all is once again good in KB2M land.... This is my third G-5500 bought in 2009, the first one was bought used, and when I replaced it when over 20 years old, second one is in Florida, acquired used age unknown. I'm thinking when assembled, someone forgot to Locktite the set screw on this one. Geezzz...
To all my sat buddies, I will be back OTH tomorrow afternoon....
